' To all whom t may concern) Be it known that I, CLYDE N. ENGLAND, a citizen of the United States, residing at Fort Flagler, in the county of Jeiferson and State of Washington, have invented certain new and useful Improvements in Envelops, of which the following is a spec-ification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in envelops and mo-re particularly to an envelop provided with means to prevent breaking of the seal thereof without detection and my object is to provide av device of this character which will be positivein its action.

A further object of the invention resides in providing an envelop having an inner Y removable card to aid in the sealing of the device and a. still further .ob]ect resides in providing an envelop which 1s extremely simple and durable in construction, ine.-

pensive to manufacture and one which will be very eflicient and useful in operation.

With these and other objects in view, the

invention consists in the novel features of Y construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing forming a part of this application, Figure l is a plan view of the envelop in semi-folded position with parts broken away to show the manner of securing the tongue to the inserted card therein. Fig. 2 is a vertical transverse section through the envelop in folded and sealed position; and Fig. 3 is a perspective view of the card removed.

In describing my invention, I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which l indicates the body or central blank of my improved envelop on which is formed the usual end flaps 2 and 3 and the bottom flap t which are adapted to'be folded over and glued together in the usual manner. After the end and bottom flaps are properly folded and secured together to form the rear wall of the device, a horizontal slot 5 is provided about centrally therein and the upper edge of the central blank or body l is provided with the usual closing or top flap 6. An additional and smaller closing iiap 7 is also provided and glued or otherwise secured to Specification of Letters Patent.

Application led September 23, 1912.

Patented Oct. 7, 1913. Serial No. 721,903.

the inner face of the top flap 6 at its j unction'with the blank 1 and at the central portion of the free edge of said flap 7, is formed an elongated tongue or strip 8 which is adapted to be inserted through the slot 5, when the flap 7 is folded down at the time of sealing the device. ln the central portion of the flap 7, in alinement with the slot 5 and tongue 8, is an additional slot 9 and removably inserted in the envelop proper, between' the front and rear walls thereof, is a card 10. This card is provided about centrally thereof, adjacent the vupper and lower edges with the slots 11 and 12 respectively which are disposed in alinement with the slots 5 and 8 of the envelop.

When the card is inserted in the envelop, the slot 12 is below the slot 5 and is adapted to receive therethrough the tongue 8, after the latter has been inserted through said slot 5 and the tongue is continued upwardly on the opposite face of the card to be inserted through the upper slot 1l and thence through the slot 9 of the fiap 7, the latter slot registering with the slot 11 when said Hap 7 is folded down. The tongue may be cut after being inserted through the slot 9 of the flap 7 and the flaps 6 and 7 are folded down to hold the same in place, but in order to secure the tongue against movement, a securing means is provided. This is accomplished by cutting away the central lower edge of the card 10, as shown at 13 and through the plies of the card is disposed a centrally movable pin 141. This pin is formed in sections and when the lower section which has the head formedthereon is forced upwardly, the other section ofthe pin is also forced Vupwardly to cross the slot 12 and secure the tongue 8 against the wall of the card. The cutaway portion of the card willadmit of the pin `being normally drawn outwardly and readily envelop until the lower edge of the same engages the lower edge of the envelop and the free end of the elongated tongue 8 is then passed through the upper slot 11 in said card. It will be understood that througho ut the operation thus far described, the elongated tongue 8 is slack in its length so that the parts of the envelop may be spread to permit the fingers of the operators hands to be readily inserted therein to pass the tongue through the various slots mentioned. After passing the tongue through the last mentioned slot ll of the card, the slack in the tongue is somewhat taken up by drawing said tongue upwardly and the free end of the tongue is then passed through the slot 9 of the additional closing flap 7. The elongated tongue 8 is then drawn, taut and said closing Hap 7 folded downwardly. The lower portion of the pin 14 in the card l0 is then forced upwardly which will obviously force the upper or pointed portion of said pin upwardly to secure said tongue against the face of the card and the elongated tongue 8 is then cut off just below the slot 9 on the outer face of the flap 7. The main closing fiapA 6. is then sealed in the usual manner on the rear wall of the envelop which is coniposed of the end and bottoni fiaps and it will be seen that having once sealed the envelop in this manner, the same may not be unsealed, without detection.

From the foregoing it will be seen that I have provided a simple, inexpensive and efficient means for carrying out the objects of the invention and while I have particu-u larly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form., proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described this invention., whatI claim is l. An envelop of the class described comprising a body blank forming. a front wall, end and bottom flaps formed thereon to form a rear wall, said rear wall being prof vided with a slot, a closing flap formed on Copies of this patent may be obtained-'for fiveA cents each, by addressing the Commissioner of Patents,

the upper edge of said front wall, an additional and smaller closing flap formed on Ysaid other closing flap, said latter closing flap-being'also provided with a slot, a meinber inserted between said front and rear walls and also provided with a pair of slots, Y

a tongue formed on the last mentioned closing Hap and adapted for introduction thro-ugh the slots of said rear wall, inserted `meniber, and said last mentioned closing flap, and separable means to secure said tongue in engagement with said inserted member.

2. An envelopof the class described com-V ing flap formed on the upper edge ofv the rear wall, an additional closing flap carried on said other closingy flap, said latter closing flap. being provided with a slot, a card inserted between said front Vand rear walls, said card being also provided with slots, a tongue formed on said additional Vclosing fap and adapted for insertion through the slots, of said rear wall, card and said last mentioned closing flap., and means carried on said card to secure said tongue thereto.`

3. The combination with an envelop of suitable design having a tongue on the closing flap thereof and also provided with a slot in the rear wal-l to receive said'tongue therethrough; of a card introduced in said envelop, said card; being provided with a slotto receive said tongue therethrough andalso having the lower edge thereof cut-away to, forin a cavity, and a pin slidably disposed through said card from the cavity therein,A said pin being adapted to cross the slot in said: card to engage said tongue` extendingV therethrough, whereby the latter will be l secured to the card.

In testimony whereof I hereunto affix my signature inthe presence of. two witnesses.
